MACHINE FOR MAKING ICE-CREAM (JONES.

To all whom it may concern:

Be it known that I, KARL WESSEL, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Machines for MakingIce-Cream Cones; and I do hereby declare the following to'be a full,clear, and exact description of .theinvention, such as will enableothers skilled in the art to which it appertains make and use the same.

My present nvention relates to pastry machines, and .3 especiallydirected to the improvement ,of machines for making ice brokenaway-showing several of the two.

cream cones.

Generally stated, the invention consists of the novel'devices. andcombinations of devices hereinafter described and defined in the claims.

More particularly, the present machine is designed as an improvement onor modification of that machine disclosed and claimed broadly in myprior co-pending application, S. N. 446,651, filed of date, August 3rd,1908, and entitled Machine for making ice cream cones.

.In this machine, as in the machine in my prior application, I employ-aseries of mold sections that are movable on an endless orbit or circuit,and a cooperating loose series of mold sections arranged to. be set incooperative relation in respect to the first series and to be separatedtherefrom. A baking device or means is provided for action on the moldsections while they are moved in cooperative relation in respect to eachother. Preferably, automatic means is employed for separating themold-sections and bringing the same together with a properly timedaction, and dough supplying means is also provided for ejecting doughinto the receiving molds while the cooperating molds or plungers areremoved therefrom.

The machine is preferably constructed as illustrated in the accompanyingdrawings, wherein like characters indicate like parts throughout theseveral views. Referring to the drawings,

Fig. 11 is a fragmentary detail showing a portion of one of theso-called transferring chains and portions of one of the independentlyremovable bars; and

Figs. 12 and 13 are details in section showing the construction of thereceiving molds.

The framework of the machine is made up of laterally spaced bearingplates 1 and pedestals 2, the latter being rigidly secured on theformer, the said laterally spaced parts being connected by suitableties. verse driving shaft 3 is journaled; on the frame plates 1, and, atone end, is provided with a large spur gear 4, that meshes with a spurpinion 5, carried by the hub of a driving sheave 6. This driving sheave6, and an idle-driving sheave 7, are loosely journaled, side by side, ona large stud 7 that projects from one of the frame plates 1. Journaledinthe frame plates 1 both in front andat the rear of the. driving shaft3 are heavy sprocket shafts 8, each of which car- A transmolds 10, andconical cores or plungers 11.

The members 10 are the dough receiving members, and these are carried bymold bars 12, while the cores 11 are carried by the mold bars 13.Preferably, the bars 12 are pivotally connected or hinged at 14, to forma sort of endless chain, and they are arranged to run in the manner of asprocket chain over the sprockets 9, of the sprocket shafts 8. Thesemold bars 12 are arranged to travel on an endless orbit. The mold bars13 are independently removable from the cooperating mold bars 12, andthey are arranged to travel on a difierent but intersecting orbit, bymeans of an automatic so-called transferring device. However, so far asthe broad idea of this invention is concerned, the said cone bars 13might be removed and applied by hand operations. Otherwise stated, themold bars 13 are dismountable from the machine, either by hand or byautomatic mechanism, but preferably the latter. For imparting a step bystep movement to the traveling endless series of mold bars 12, one ofthe shafts 8 is provided at one end with a ratchet wheel 15, which isengaged by a long driving dog 16, pivotally attached to a short crankarm 17, carried by the adjacent end of the driving shaft 3. The crank 17is of such length and the teeth of the ratchet wheel 15 are in suchnumbers, that for each operative stroke of the dog 16, the series ofmold bars 12 will be moved just the distance represented by the width ofone of the said bars. To accurately set the dog 16 for the abovedescribed action, it is shown as made in two sections connected by aturn buckle or threaded sleeve 16. The core plungers 11, for animportant reason, instead of being rigidly and immovably secured to therespective bars 13,- are mounted therein so that they are capable ofslight rotary and endwise movements in respect thereto, the purpose ofsuch movement being to loosen the. plungers from the baked cones whilethe latter are still within the molds 10 of the bars 12.

As shown, the mold bars 12 are provided each with two rows of receivingmolds l0, and the mold bars 13 are provided each'with two rows of cores11. Small cap plates 18 (see particularly Figs. 6 and 7) arerigidlysecured by screws, or otherwise, to the upper ends of the cores 11, andthese are provided 13. Hence, as is evident, when the bar 19 is movedendwise, all of the cores 11 of that particular mold bar will besimultaneously given a slight rotation sufficient to break the tween thehead 27 and the adjacent bearing 26 tends to hold the connecting bar 19pressed downward or toward the mold bar .13, and toward the left inrespect to Figs. 6

and 7, and in such position of the said parts, the mold cores 11 will beextended for proper coiiperation with receiving molds 10 in which theyare adapted to then be inserted.

When the operating rod 25 is pressed toward the right in respect toFigs. 6 and 7 the first effect thereof is to impart the above notedslight rotation to the mold cores, and the second effect thereof, is toraise the connecting bar 19, and to slightly move the cores 11 endwise,outward from the molds 10, thereby completely releasing the cores fromthe baked cones. Otherwise stated, the so-called cores are loosened fromthe baked cones by a spiral receding movement. At the proper time, thehead 27 of the operating rod 25 will, under advance movement of theendless series of mold bars 12, be engaged and pressed toward the-right,as above stated, by engagement with a cam flange or plate. 29, securedin respect to themachine frame, (see Fig. 3).

In this preferred arrangement of the two series of mold-equipped bars,the said bars are arranged to be held in cotiperative relation inrespect to each other, while traveling together a certain distance, bymeans of suitable clamps applied thereto. The said bar clamping means ispreferably, substantially as shown in the drawings, and best illustratedin Figs. 6 and 7, by reference to which, it will be noted that clampingyokes 30 are pivoted at their lower ends to depending lugs 31 on theends of the mold bars 13. At their upper free ends, the yokes 30 areprovided with projecting stems 32, the inner ends of which are beveledand are adapted to cam themselves into engagement with shallow notchesformed in the ends of bars 33. that are secured to and project from theends of the mold bars 13. When the clamping devices 30-32 are engagedwith the bar extensions 33, as shown by full lines in Fig. 7, thecoiiperating bars 12 and 13 will be locked together, with the moldmembers 10 and 11 in cot'iperative relation. When, howing from brackets37 secured to; the side' Further action of these cam,

ever, the said clamping devices are moved outward, as indicated bydotted lines at the left'in Fig. 7, the said bars 12 and 13 are unlockedand the latter may be removed from the former. Means is provided forautomatically engaging the bar locking devices with the bar extensions33 and for disengaging the same at the proper times. Under movement ofthe upper bars 12 from the right toward the left in respect to Figs. 1and 3, the stems 32 of the'lock devices are engaged with obliquely fixedcam plates 34 shown as secured to, and depending from brackets 35 which.in turn, are rigidly secured to the frame plates 1. Attention" is herecalled to the fact that, as shown, a cam 29, which operates on the head27, is shown as formed integral with one of the cam plates 34. Reverselyset oblique cam plates 36 operate on the stems 32 of the lock devicefarther toward the left. As shown, these cams 36 are rigidly secured toand dependframes 1. plates 34 and 36 will begiven in the description ofthe operation.

Located between the front cam plates 34 and rear cam plates 36 and abovethe mold bar 12, which is positioned midway between these cam plates, isa dough supplying hopper, or receptacle 38 that extends between, and isrigidly secured to the frame pedestals 2. The bottom of this hopper 38is provided with perforations located one overeach of the receivingmolds 10, of the intermediately lying bar 12, and each such dischargeopening is normally closed by the conical lower end of a plunger valve39. The upper portionsof the plunger valves 39 work through guiding hubsof a guide bar 40 rigidly secured to the top of the hopper 38, and, tothe extreme upper ends, are rigidly secured to a cross head 41. The endsof the cross head 41 are connected to the lowerends of the eccentricrods 42 provided at their upper ends with longitudinally slotted heads43. These slotted heads 43 move vertically on, and are guided by a shaft44 journaled in suitable bearings 45 on the upper ends of the framepedestals 2. At their extreme upper ends, the heads 43 are provided withlat- (erally projecting lugs 46 that are supported or cams 47 secured tothe shaft 44 and located one on each side of each of said heads 43.

The independently removable mold bars 13, in addition to the projectinglock bars 33, are provided at their ends with long laterally spacedlifting rods 48 that are rigidly machine is accomplished automaticallyby an automatic mechanism provided for that portions, are pivoted at 54to certain of I the chain'links, so that they are/gravityheld invertical depending positions throu hout the movements of the said chains49. 6n'their inner faces, the lifting heads 52 are formed with bucketsor recesses that receive and properly hold the ends of the endless bars48 of the movable mold bars 13.

LA more exact relation of these parts will more fully appear in thedescription .of the operation. Y

The frame plates 1 are provided with horizontal channels at the lowerportions of which (see Fig. 2) are guide flanges 55 on which'the ends ofthe handle bars 48 may rest. The timing and relation of the parts abovedescribed will more fully appear in the description of the operation.

Figs. 1 and 5 show a form of baking device which I preferably, employ,and of ,the

parts of which,the numeral 56 indicates an upper pair ofgas supplyingpipes, 57 indicates a lower pair of gas supply pipes. The gas supplypipes 56 terminate in a per forated twyer, or nozzles 58 that areadapted to direct the flame into the downturned receiving molds 10 whichare on the upper bars 12. -The lower. pipes 57 are provided withperforated twyer or nozzle pipes 59 that are adapted to apply the flamesdirectly' to the mold bars 13 that are at the lower and upturned movingsections of the endless traveling chain made up of the mold bars 12. Thegas pipes 56 and 57 as shown,

all receive from a common gas supply pipe .60, indicated in part in Fig.1.

The receiving molds 10, in some instances, may be cast integral'with thebars 12, but they are preferably formed separately therefrom andconnected therewith by threaded engagement, as indicated in Fig. 12, orby an opposite end portion, as indicated in Fig.

13. The receiving molds, however, are terminated in short annular edges10, as best shown in Fig.12, or by a serrated sharp edge 10", indicatedin Fig. 13. These sharp edges serve to nearly, or quite, cut off thebaked cones from the sheet, or flange of dough formed by overflow of thedough from the receiving molds when the are inserted into the same.

Operation.

The operation of'the machine is substantially as follows: 1%

cores 11 When the driving shaft 3 is continuously driven, by throwingthe belt on the pulley 6, intermittent, or step by step movements willbe imparted to the endless chain of moldequipped bars 12. At thetermination of each such intermittent movement, one of the mold bars 12will be positioned with its receiving molds 10, directly below thecorresponding dough discharge passages in the bottom of the hopper 38.l/Vhile the mold bars thus remain stationary in this position justindicated, the plunger valves 39 will be raised and permit the properamount of dough to bedischarged from the hopper 38 into the underlyingreceiving molds 10. The dough discharge passage and hopper will be againclosed before the next move ment is imparted to the mold bars.

In the idle and normal position just in dicated, and best illustrated inFig. 1, one of the mold bars '13 stands in a position to be picked upfrom the mold bar 12 with which it has been cooperatively positioned,

- and another mold bar 12 stands in position to be picked up by thetransferring device and another mold bar 12 stands in position, justahead of the filling point, to have a mold bar 13 delivered thereto bythe said transferring device. More specifically stated, the transferringchains 49 are moved while the endless series of mold bars 12 remainstationary, and the one pair of gravity arighted carrying heads 52,catch the ends of the lifting bars 48, just at the rear of the fillingpoint, and carry the mold bar 13, which is just at the rear of thefilling point, first into an elevated position, and then forward of thefilling point, and then downward and deposit the said mold bar 13 incooperative relation in respect to the .mold bar 12 which is just infront of the filling point. Two movements of the series of mold bars 12are required, in the arrangement shown, to carry a lifted mold bar 13from engagement with the one bar 12 into engagement with forward bar 12,and one mold bar 13 will always be in an upliftedposi tion. By thuslifting the mold bars 13 and returning the same in cooperative relation,in respect to another mold bar 12, the mold bar 12 at the so-calledfilling or discharge pbint, is uncovered, while the dough in the properquantity is supplied to the receiving molds 10 thereof.

After the dough is deposited in the molds of the bars 12, and the bars12 and 13 are thereafter brought into cooperative relation, they aremoved, step by step, nearly to the filling point and throughout thetravel, they are subjected to the heat from the twyers, or nozzle pipes58 and 59.

The fixed cam 29 operates on the head 27 of the rod24= after the bakinghas been completed and just before the mold bars reach the positionwhere they are to be separated This spiral receding movement isimportant because it primarily loosens the cores by a twisting movement.and immediately recedes from the baked brittle cones, so that the latterwill not be cracked or broken if there is a slight irregularity in thecores. This, as is evident, loosens the cores from the baked cones sothat the latter will not adhere thereto. At about the same time, thatthe head 27 is engaged with the fixed cam 29, as above described, thefixed cams 34, on both sides, simultaneously engage the stems 32 of thelock yokes 30, and positively force the same outward and thereby releasethe same from engagement with the projecting bars. 33 of the mold bar13, which is next to be lifted by the transferring device.

After the mold bar 13 has been again deposited in cooperative relation,in respect to the mold bar 12, which is in front of the so-calledfilling point, the next following movement of the endless series of bars12,

forces the stems 32, of the lock yokes 30, into engagement with thefixed cams 36, on both sides of the machine, and these camssimultaneously force the lock yokes 30 back into locking engagement withthe end bars 33 of the said core bar 13. In this way, it will be seenthat the two classes of core bars are automatically interlocked,automatically again re-assembled in cooperative relation and thenautomatically locked together so that they are ready for their journeypast the baking devices. In fact, this machine, as preferablyconstructed, is automatic in all of its actions requiring only that thebaked cones be removed from the molds 10 "different forms, depending onthe form of the article which it is desired to make.
